...personally, I could have sex with women. I could also have sex with men, sheep, dogs, sea slugs, what have you.

Given a choice in the matter, however, I would honestly prefer to just masturbate myself - since mad, passionate love with my gf is lawfully unlikely.

::shrug::

Given what you've described about yourself, the best way for me to analogize to your life is this :

You probably could whip out your dick and smear it all over your computer monitor without too much personal difficulty/revulsion/what have you.

If you kept doing this, you would probably even be physically brought to orgasm.

Is this something you at all particularly want to do? Wouldn't even masturbating alone with your hand be more interesting?

In a society in which, culturally, everyone was heavily expected/pressured to smear their genitalia upon computer monitors, a fair number of uninterested people would, I'll wager.

If decent company popped out of the deal somehow, it'd even have some slight appeal.

I have no intentions of wiping my phallus upon my screen.

...and...

I don't think someone who has the option can really understand what it's like to have absolutely no options at all.

As per the analogy above, I have the option.

Is it really that different in terms of valid options?
